【摘要】 目的:探讨儿童恒前牙冠折露髓患儿不良预后的危险因素。方法:选取2014年1月-2017年12月本院收治的恒前牙冠折露髓患儿82例。按照预后结果将其分为预后良好组(n=67)与预后不良组(n=15)。患儿均采用行活髓切断术治疗,分析患儿不良预后的影响因素。结果:预后良好组露髓孔直径>1 mm、口腔溃疡、牙髓暴露时间>24 h、牙龈炎及牙周炎例数与预后不良组比较,差异均有统计学意义(字2=9.160、6.200、11.260、6.090、5.690,P=0.003、0.013、0.000、0.014、0.017);多因素分析显示,牙髓暴露时间>24 h、牙龈炎及牙周炎均是患儿不良预后的影响因素(P=0.001、0.000、0.000)。结论:牙髓的暴露时间及口腔疾病是儿童恒前牙冠折露髓出现不良预后的危险因素。

【Abstract】 Objective:To investigate the risk factors of poor prognosis in children dental pulp exposure after constant anterior crown fracture.Method:A total of 82 children dental pulp exposure after constant anterior crown fracture who treated in our hospital from January 2014 to December 2017 were selected.According to the outcome of the prognosis,they were divided into good prognosis group(n=67) and poor prognosis group(n=15).All children were treated with pulpectomy,and the factors affecting the poor prognosis of children were analyzed.Result:The diameter of the pulp hole >1 mm,oral ulcers,the time of dental pulp exposure >24 h,gingivitis and periodontitis cases in good prognosis group were compared with poor prognosis group,the difference were statistically significant(字2=9.160,6.200,11.260,6.090,5.690,P=0.003,0.013,0.000,0.014,0.017).Multivariate analysis showed that the time of dental pulp exposure >24 h,gingivitis and periodontitis were the risk factors for poor prognosis in children(P=0.001,0.000,0.000).Conclusion:Dental pulp exposure time and oral diseases are the risk factors of unfavorable prognosis of children dental pulp exposure after constant anterior crown fracture

恒前牙冠折露髓是一種常见的牙病,具有较高的发病率,且儿童是该牙病的高发人群,儿童恒前牙冠折露髓主要是由外伤造成的,且出现恒前牙冠折露髓时,患儿的恒前牙根尖仍处在发育的时期,通常采取活髓切断术进行治疗,完整的保存牙的根部,保持患儿的牙髓活力,促进牙根可继续正常发育[1-2]。尽管活髓切断术是一种治疗恒前牙冠折露髓的主要方法,但部分患儿会出现不良预后的情况,因此对恒前牙冠折露髓不良预后的情况进行分析,有利于防治不良预后问题的发生[3-4]。本研究选取2014年1月-2017年12月本院收治的82例恒前牙冠折露髓患儿为研究对象,对恒前牙冠折露髓患儿不良预后的危险因素进行探讨分析。现报道如下。……p>
